I have owned a ym1720D for about 10 years and have had no real problems out of it. I just had a new clutch put in it, but that is about the only thing I have done that required the tractor to be down for any time. I have not had a problem getting any parts, but have had to wait for them to be shipped to my house. The only down side I can see is a few safety items that may not be on the tractor, which can be added and waiting a week or two for parts. Otherwise they seem to be everybit as dependable as their American counterparts and priced cheaper. I have noticed that some of the parts are also cheaper.
